I currently use Wells Fargo and it’s a pain in the butt to keep going there in person and setting up a security deposit account.

Look into a DSCR, Debt Service Coverage Ratio, loan where the rental income can be used to qualify the cash out refinance instead of your personal income.To Your Success! 

It would just need to be a situation where they have great contact with the person doing that managing of the project (I.e. have known the person for years, great reputation, person has experience in flipping etc.).

The person calling you is on a money grab. you do not need a wyoming trust. 

Is there a point of contact person/business that handles all home investor concerns (general contractor, engineer, etc.)

Be candid and do it in person.

For the first few years, I would focus more on the experience you gain than the money you earn.

You are a high w2 earner, The house is worth 110k today, you are buying from your grandma for 60k in exchange for free rent for life, upside ARV of 200k.The costs of owning the house will help provide tax relief on your high w2 earnings, you are buying a great chunk of equity that will pay off in the future, and you and your grandma are doing each other solids. 

I will make that proposal to the person I am talking and see where it goes.

For example, they won't need to cover your personal belongings (furniture, clothing, etc.) because you won't be living there.A landlord policy should cost about the same as a homeowner's policy; it just changes what is covered.
